The disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which various embodiments are shown. This disclosure may, however, be embodied in many different forms, and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Like reference numerals refer to like elements throughout.

It will be understood that when an element is referred to as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

It will be understood that, although the terms “first,” “second,” “third” etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,” “component,” “region,” “layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, "a", "an," "the," and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. For example, "an element" has the same meaning as “at least one element," unless the context clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.” “Or” means “and/or.” As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” can mean within one or more standard deviations, or within ± 30%, 20%, 10% or 5% of the stated value.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.

An electronic device may wirelessly obtain electric power from an external electronic device to charge a rechargeable battery within the electronic device with the obtained power. For the electronic device to wirelessly acquire the power, at least one coil in the electronic device needs to be located within a certain distance from at least one coil in the external electronic device. Accordingly, in the case where the electronic device is mounted onto or positioned relative to the external electronic device with the at least one coil of the electronic device being spaced apart from the at least one coil in the external electronic device over a certain distance, a user of the electronic device may receive a kind of notification to be served in the electronic device as an alarm.

The electronic device, in use, may provide either a folding state or an unfolding state through a flexible display, or provide either a state in which a part of a display area of ​​the flexible display is rolled up or a state in which the entire display area of ​​the flexible display is exposed. The efficiency of wirelessly acquiring the power from any external electronic device may change depending on different states of the electronic device, and therefore, a scheme of enabling the electronic device to provide the notification on different information according to various states of the electronic device in use may be implemented.

1 FIG.A illustrates examples of an environment including an electronic device and an external electronic device according to an embodiment.

1 FIG.A 100 101 102 101 102 101 101 102 101 101 102 101 Referring to, an environmentmay include an electronic deviceand an external electronic device. In an embodiment, the electronic devicemay be a device that wirelessly acquires electric power from the external electronic deviceto charge at least one rechargeable battery in the electronic device.

For example, the distance between the at least one coil of the electronic deviceand the at least one coil in the external electronic devicemay vary depending on how the electronic deviceis mounted on or positioned relative to the external electronic device. For example, on condition that the electronic deviceis aligned with the external electronic device, as in an arrangement, an arrangement, and an arrangement, respectively, the at least one coil within the electronic devicemay be properly adjacent to the at least one coil within the external electronic device. The charging efficiency may be represented as a first value in an arrangement in which the at least one coil in the electronic deviceis adjacent to the at least one coil in the external electronic device.

The charging efficiency may be represented as a second value lower than the first value, in an arrangement in which the at least one coil in the electronic deviceis located spaced apart from the at least one coil in the external electronic deviceover the certain distance. In other words, the charging efficiency when the electronic deviceis mounted on or positioned relative to the external electronic devicein an arrangement (e.g., one or more of the arrangements,, and) of being not properly aligned with the external electronic devicemay be lower than the charging efficiency when it is mounted on or positioned relative to the external electronic devicein an arrangement (e.g., one or more of the arrangements,, and) of being fittingly aligned with the external electronic device. Accordingly, on condition that the electronic deviceis not fittingly mounted onto or positioned relative to the external electronic devicefor charging the at least one battery, as seen in each of the arrangements,, and, the electronic devicemay control to provide a notification or information as an alarm or alert.

For example, the first wireless signal may be a signal distinct from the wireless signal received in the operationof. For example, the first wireless signal may be a signal transmitted from the external electronic deviceto identify whether the electronic devicepositioned relative to the external electronic devicerequires charging of the power. For example, the external electronic devicemay transmit the first wireless signal, in order to identify that an object comes into contact with at least a part of a housing of the external electronic device, and based on the identification, identify whether the object brought into contact with the part is a device requiring charging of the power like the electronic deviceor any other foreign matter.

However, it is not limited thereto.

110 150 150 150 In an embodiment, the designated power may be identified based on time of day. For example, the processormay store information on the charging history of the batterywhenever the batteryis charged, and identify the designated power based on the power obtained in hours when charging of the batteryoccurs most frequently from the stored information.

For example, the first state may be the first state defined through the description of, and the second state may be the second state defined through the description of. For example, since the electronic devicein the second state providing a larger size than the electronic devicein the first state is more likely to be unstably mounted on or positioned relative to the external electronic device, the processormay identify whether the state of the electronic deviceis the first state or the second state. In an embodiment, the processormay execute operationon condition that the electronic deviceis in the first state, and execute operationon condition that the electronic deviceis in the second state.

13 FIG.A 1306 1304 1304 1306 101 110 1308 101 110 1310 110 1311 110 1308 101 110 1310 101 110 1311 shows an example of executing the operationafter executing the operation, but it is only for convenience of description.

For example, the first screenmay be superimposed on a lock screen. For example, the first screenmay be superimposed on the screen displayed through the displayimmediately before displaying the first screen, in order to inform that the electronic deviceis in a state different from the user's intention to charge the batteryof the electronic device. In an embodiment, the first screenmay further include a visual objectfor providing at least part of information in the screen disposed beneath the first screen. For example, the processormay further display in the first screena visual objectfor providing information on the local time within a lock screencovered with displaying the first screenas superimposed on the lock screen. However, it is not limited thereto. In an embodiment, at least part of the first screenmay be formed to be translucent. For example, the processormay display the first screensemi-transparently so that the user can view the information of the lock screendisposed below the first screenin the remaining area of ​​the first screenexcluding the area displaying the first information. In an embodiment, the first screenmay include an opaque area displaying the first informationand a semi-transparent remaining area. However, it is not limited thereto.

For example, the processormay increase the luminance of the first screento draw the user's attention, on condition that a specified time duration has elapsed from the timing of displaying the first screenor responsive to the occurrence of another condition. For example, the processormay increase the size of a textin order to draw the user's attention more, on condition that a specified time duration has elapsed from the timing of displaying the first screenor responsive to the occurrence of another condition. For example, the processormay change the color of the textor the visual objectto draw the user's attention more, on condition that a specified time duration has elapsed from the timing of displaying the first screenor responsive to the occurrence of another condition. For example, on condition that a specified time duration has elapsed from the timing of displaying the first screenor responsive to the occurrence of another condition, the processormay further display a visual effect around the textor the visual objectto draw the user's attention further. For example, the processormay control the displayto cause at least one of the textand the visual objectto blink, so as to draw the user's attention more, on condition that a specified time duration has elapsed from the timing of displaying the first screenor responsive to the occurrence of another condition. According to embodiments, the processormay output audio signals via a speaker of the electronic deviceor provide vibrations through an actuator of the electronic deviceto draw the user's attention further, in lieu of changing displaying of the first screen, on condition that a specified time duration has elapsed from the timing of displaying the first screenor responsive to the occurrence of another condition. However, the configuration is not limited thereto.

1310 110 101 101 101 102 101 102 102 101 102 101 In operation, the processormay display a second screen including the first information and second information for guiding to change the state of the electronic deviceto the first state, based on identifying that the electronic deviceis the second state. For example, since the width of the electronic device in the second state is wider than that of the electronic device in the first state, the stability when the electronic devicein the second state is positioned relative to the external electronic devicemay be lower than stability when the electronic devicein the first state is positioned relative to the external electronic device. For example, the stability in alignment of the external electronic deviceand the electronic devicein the second state may be lower than the stability in alignment of the external electronic deviceand the electronic devicein the first state, and therefore, the second screen may further include the second information, unlike the first screen.

In an embodiment, the second informationmay include a text guiding to change the state of the electronic deviceto the first state. Although not shown in, in an embodiment, the second informationmay further include an image or an animation for guiding to change the state of the electronic deviceto the first state.

1316 1322 1323 125 1316 1314 1316 1322 160 1316 1322 1323 125 In an embodiment, the visual objectin the second screenmay be displayed in an area adjacent to an edgeof the display, unlike the visual objectdisplayed in the center area of ​​the first screen. For example, since the visual objectin the second screenis displayed at a position corresponding to the position where the coilis disposed in the second state, the visual objectin the second screenmay be displayed in the area adjacent to the edgeof the display.

1322 1314 1322 1317 1322 125 1322 101 150 101 1322 1318 1322 1322 1314 1318 1322 1318 1314 1318 1322 1322 1318 1314 1318 1322 1324 1322 1318 1314 In an embodiment, the second screenmay be superimposed on another screen, like the first screen. For example, the second screenmay be superimposed on the lock screen. For example, the second screenmay be superimposed on the screen displayed through the displayimmediately before displaying the second screen, in order to inform that the electronic deviceis in a state different from the user's intention to charge the batteryof the electronic device. In an embodiment, the second screenmay further include a visual objectfor providing at least part of information in the screen disposed beneath the second screen. Since the size of the second screenis larger than the size of the first screen, the visual objectin the second screenmay provide more information than the visual objectin the first screen. For example, the visual objectin the second screenmay include a thumbnail image of a screen disposed beneath the second screen, unlike the visual objectin the first screen. For example, the visual objectin the second screenmay further include at least one executable elementfor executing at least one function provided through a screen disposed beneath the second screen, unlike the visual objectin the first screen. However, it is not limited thereto.

1322 1314 In an embodiment, displaying on the second screenmay change over time, as in displaying on the first screen.

For example, the wireless signal may be received via the coilfrom at least one coil of the external electronic device. For example, the processormay acquire electric power for charging the battery, using a PMIC, based on the wireless signal received through the coil. For example, the processormay obtain the power provided based on the wireless signal.

110 1404 1408 1416 110 110 1404 1408 1416 110 110 In an embodiment, the processormay perform operationand the following operationstowhile processorreceives the wireless signal. In an embodiment, the processormay perform operationand the following operationstowhile processorreceives the wireless signal and/or subsequent to the processorreceiving the wireless signal.

1404 110 101 125 125 101 270 370 200 250 260 300 350 360 125 410 450 101 101 101 102 110 101 2 3 FIG.A toB 2 3 FIGS.B andB 4 4 FIGS.A toB 4 FIG.A In the operation, the processormay identify whether the state of the electronic deviceis in either a first state or a second state. For example, the second state is defined by a first total area of an exposed portion of the display, and the first state is defined by a second total area of an exposed portion of the display, the second total area being greater than the first total area. For example, if the electronic deviceis the foldable display device illustrated in, the second state may be a fully folded state of the foldable display device as shown by stateand stateofrespectively, and the first state may be the other states except for the second state (e.g., one or more of the states,,,,, and/or). In another example, if the electronic device 101 is the rollable display device as shown in, the second state may a state in which a portion of the displayrolled into the housing as shown by the stateof, and the first state may be other states (e.g., the state) except for the second state. For example, when the electronic deviceis in the first state, and thus providing a larger size than the electronic devicein the second state, the electronic devicemay be positioned relative to the external electronic devicein an unstable manner. The processormay identify whether the state of the electronic deviceis the first state or the second state.

1406 110 101 125 101 651 684 101 651 684 1351 125 101 101 125 6 6 FIGS.B,C 13 FIG.B 6 6 FIGS.B andC 6 6 FIGS.B,C 13 FIG.B 12 FIG.B 12 FIG.B In operation, the processor, based on identifying that the state of the electronic deviceis the first state, may provide a first notification guiding to change the first state to the second state. In a state that the displayis exposed toward the outside like, or, if the electronic deviceis the foldable display device, the first notification may be provided by displaying the first notification like the fourth informationorshown in, and if the electronic deviceis the rollable display device, the first notification may be provided by displaying the first notification like the fourth information,orshown inor. In a state that the displayis not exposed toward the outside like, the first notification may be provided by audio signals through the speaker of the electronic deviceor vibrations through the actuator of the electronic device, or displaying a visual effect along at least one of the sides of the displaylike.

1408 110 101 101 1410 110 101 102 110 125 102 12 FIG.B In operation, the processormay detect whether the electronic deviceis in the second state. If the electronic deviceis in the second state, in operation, the processormay identify whether there is a display exposed toward the outside of at least one display of the electronic devicemounted on the external electronic device. In other words, the processormay identify whether a surface of the housing on which the displayis not disposed faces away the external electronic devicelike.

1412 110 101 102 777 12 FIG.B 7 FIG.C In the operation, the processor, based on identifying that there is no display exposed to the outside, may provide a second notification to guide that the electronic deviceis abnormally positioned relative to the external electronic device. As an example, when no display is exposed to the outside (e.g., visible), it means that there is no display in a state of being viewed by the user, and therefore, the second notification may be provided by means of at least one of audio signals, vibrations, or blinking like the ways explained above with reference to. As an example, when no display exists exposed to the outside, it means that there is no display in a state of being viewed by the user, and therefore, the second notification may be provided using another device, such as the wearable deviceshown in.

1414 110 101 102 101 102 160 101 102 In operation, the processormay identify whether the electronic deviceis properly aligned with the external electronic device. For example, the proper alignment may be determined by whether the electronic deviceis positioned relative to the external electronic devicein an arrangement that a distance between the center of the coilin the electronic deviceand the center of at least one coil in the external electronic deviceis within a certain distance (e.g., 1 cm).

1416 110 101 102 101 102 In the operation, the processormay display a screen including information to guide the electronic deviceto be aligned with the external electronic device, based on identifying that the electronic deviceis not fittingly aligned with the external electronic deviceusing the ways explained herein.

101 101 101 101 150 101 102 As apparent from the foregoing, the electronic devicecan adaptively display a screen according to the state of the electronic device.
